First, we need to recall the formula for the circumference of a circle, which is C = Pi * d. Here, 'C' stands for the circumference, 'Pi' is a mathematical constant whose approximate value is 3.141592653589793, and 'd' is the diameter of the circle.
Now, we are asked to rewrite this formula and solve for Pi.
To do this, we can follow the below steps:
Step 1: We start with the formula C = Pi * d.
Step 2: Next, we need to separate Pi from the rest of the terms. Since Pi is being multiplied by 'd', we can use the property of equality that states that if two values are equal, then we can divide both sides of the equation by the same non-zero number to remain with an equivalent equation.
Step 3: Thus, we divide both sides of the equation by 'd'. This gives us (C/d) = Pi.
So the equivalent expression for Pi is C/d. This means that Pi could be equivalently described as the circumference of a circle divided by its diameter.
